PUMP CONNECTION.

Specification of Letters Patent.

Patented Apr. 4, 1911.

Application filed July 8, 1910. Serial No. 570,960.

To all whom it may concern:

Be it known that I, CARL PAETZ, a citizen of the United States ofAmerica, residing at Algona, in the county of Kossuth and State of Iowa,have invented certain new and useful Improvements in Pump Connections,of which the following is a specification, reference being had thereinto the accompanying drawing.

This invention relates to couplings for use in connecting a windmill orother motor to a pump, and the principal object of the same is toprovide a device of the character described which may be readilymanipulated to make the connection between the motor and the pump arigid one so that the motor will operate the pump, or to make theconnection a loose one so that the pump can be operated independent ofthe motor.

In carrying out the objects of the invention generally stated above itwill, be understood, of course, that the essential features thereof arenecessarily susceptible of changes in details and structuralarrangements, one preferred and practical embodiment of which is shownin the accompanying drawings, wherein Figure 1 is a perspective view ofthe improved coupling. Fig. 2 is a top plan View. Fig. 3 is a verticalsectional view taken on the line 3-3, Fig. 2. Fig. 1 is a fragmentarysectional view of the coupling showing the slidable connection of thelocking frame with the housing.

Referring to the accompanying drawings by numerals, 1 designates thehousing of the improved coupling into the openupper portion of which thewindmill or other motor rod 2 extends and which is detachably locked inrigid relation therewith by the bolts 3 and nuts 4, or other type offastening means. The base 5 of the housing 1 is provided with a centralvertical opening 6 through which the pump rod 7 is slidable. Said base 5is also provided with a central horizontal opening 8 that insersectsopening 6. Externally each side of the housing is provided with atransverse guiding groove 9, said grooves being adjacent the lower endof said housing.

A locking frame 10, preferably formed of a single length of metal bentinto a substantially rectangular open frame, has the side membersthereof slidably mounted in grooves 9, said frame being arranged atright angles to housing 1 and surrounding the base thereof. The forwardend of the frame 10 terminates in the parallel spaced cars 11 which areconnected by the shaft 12. Said shaft is preferably a bolt that is heldin engagement with the cars 11 by the head 13 and nut 14.

A cam lever 15 is carried by shaft 12 and is adapted to slide frame 10transversely of housing 1. when rocked in one direction. Said shaft 12is also provided with a locking bolt 16 that is slidable through theopening 8 of base 5 to engage one of the openings 17 of pump rod 7 tolock said rod to the housing 1.

Housing 1 has one end of a plate 18 fas-' tened to the rear surface, thefree end of said plate extending through frame 10 and across the rearend of opening 8. Said plate carries a laterally projecting bar 19 thefree end portion of which is slidable through a transverse guide opening20 formed through the rear end of frame 10. A spring 22 is coiled aboutbar 19, one end of said spring bearing against plate 18 and the otherend bearing against the rear end of frame 10, so

that plate 18 is normally held in contact with the rear surface ofhousing 1.

As is shown in Fig. 1 of the accompanying drawings, the pump rod 7 islocked to the housing 1 by means of the bolt 16 which projects throughthe opening 6 of the base 5 of said housing, the locking operation beingperformed when the cam head of rocking lever 15 is clear of base 5 andthe tension of spring 22 projects frame 10 rearwardly and carries withit the said locking bolt. To release the pump rod 7, the cam lever isrocked to a position parallel to housing 1, which causes the head ofsaid lever to contact with base 5 of housing 1 so that frame 1.0 willslide forward against the tension of spring 22, and remove bolt 16 fromengagement with rod 7.

It will be seen from the foregoing that the invention provides simplemeans whereby the lever 16 is manually operated to engage the pump rodto, or release the same from, the motor.

What I claim as my invention is:--

1. A coupling comprising a housing having an opening in its base for thereception of a pump rod. said base provided with a transverse opening, aplate fastened to the rear of said housing and extending over the saidtransverse opening, a locking frame embracing the base of said housingand slidable transversely thereof, a guide bar car ried by the saidplate and extending through the rear of said frame, a spring coiledabout said bar for projecting said frame rearwardly a shaft carried bythe forward end of said frame, a locking bolt carried by said shaft andslidable in the base opening of the housing, and a cam lever carried bysaid shaft for moving said frame transversely of the housing against thetension of said spring.

2. A coupling comprising a housing provided with a transverse opening, aframe slidable transversely of said housing, said frame being providedwith a transverse rear opening, a plate fastened to the rear of saidhousing and having a free end overlapping the opening therein, a lockingbolt carried by the forward end of said frame and adapted for engagementwith the opening in the housing, a bar projecting laterally from theplate and slidable in the opening of said frame, a spring coiled aboutsaid bar for normally holding the frame in position, to retain thelocking bolt in engagement with the opening of'the housing, and meansfor moving said frame against the tension of said spring to release thelocking bolt from the housing opening.

In testimony whereof I hereuntoaflix my signature in presence of twowitnesses.

CARL PAETZ.
